MATERIALS AND METHODS: A total of 8966 voluntary school students aged 13-15 years old were recruited for scoliosis screening. Screening was done by measuring the angle of trunk rotation (ATR) on forward bending test (FBT) using a scoliometer. ATR of 5 degrees or more was considered positive. Positively screened students had standard radiographs done for measurement of the Cobb angle. Cobb angle of >10° was used to diagnose scoliosis. The percentage of radiological assessment referral, prevalence rate and PPV of scoliosis were then calculated.

RESULTS: Percentage of radiological assessment referral (ATR >5°) was 4.2% (182/4381) for male and 5.0% (228/4585) for female. Only 38.0% of those with ATR >5° presented for further radiological assessment. The adjusted prevalence rate was 2.55% for Cobb angle >10°, 0.59% for >20° and 0.12% for >40°. The PPV is 55.8% for Cobb angle >10°, 12.8% for >20° and 2.6% for > 40°.

METHODS: This cross-sectional study was conducted between August 2020 and January 2021, in the Infectious Disease clinic and ward. One hundred ninety-one patients were recruited via convenience sampling. Patients' sociodemographic were obtained, followed by Depression, Anxiety, Stress Scale -21 (DASS-21), Multidimensional Scale of Perceived Social Support (MSPSS), and M.I.N.I. international neuropsychiatric interview (M.I.N.I.) The cut off DASS-21 point for depression is ≥5, for anxiety, ≥ 4. Mann-Whitney U and Chi square test were used to analyse the association between variables, and logistic regression to find predictability.

RESULTS: Of the 191 participants, 89.5% outpatient, mean age 40 years (SD 0.742), 91.1% male, 65.4% single, 71.2% working, 46.1% Malaysian Chinese, 59.8% non- heterosexual, mean 6 years of being HIV positive; mean CD4 count 449/μL; mean viral load 116,690 (median = 20). 85.9% were taking antiretroviral therapy. The prevalence of depression was 35.1% (n = 67); anxiety was 42.9% (n = 82). Regression analysis revealed anxiety and stress increased odds of depression by 3.8 times (p = .001) and 12 times (p < .001) respectively. Those 40 years old and younger had 2.3 times odds of anxiety (p = .048). Increased social support from friends increased odds of anxiety by 1.7 times (p = .018). Depression and stress increased odds of anxiety by 4.4 times (p = .001) and 3.7 times (p = .008) respectively.

METHODS:: This was a retrospective propensity score-matched study using prospectively collected data. Surgeries performed between 08:00 and 16:59 h were labeled as daytime surgeries (group 1) and surgeries performed between 17:00 and 06:00 h were labeled as after-hours surgeries (group 2). The perioperative outcome parameters were average operation time in and out, operation duration, intraoperative blood loss, blood transfusion, intraoperative hemodynamic parameters, preoperative hemoglobin, postoperative hemoglobin, and total patient-controlled anesthesia (PCA) morphine usage. Radiological variables assessed were Lenke subtypes, preoperative Cobb angle, number of fusion levels, number of screws used, postoperative Cobb angle, correction rate, side bending flexibility, side bending correction index, complications rate, and length of hospitalization.

RESULTS:: Average operation time in for daytime group was 11:32 ± 2:33 h versus 18:20 ± 1:05 h in after-hours group. Comparing daytime surgeries with after-hours surgeries, there were no significant differences ( p > 0.05) in the operation duration, intraoperative blood loss, intraoperative pH, bicarbonate, lactate, postoperative hemoglobin, hemoglobin drift, blood transfusion, postoperative Cobb angle, correction rate, side bending flexibility, side bending correction index, length of hospitalization, and complications rate. Total PCA morphine usage was significantly lesser in the after-hours group (18.2 ± 15.3 mg) compared with the daytime group (24.6 ± 16.6 mg; p = 0.042).

OBJECTIVE: The aim of this study was to determine the feasibility of an accelerated recovery protocol for Asian adolescent idiopathic scoliosis (AIS) patients undergoing posterior spinal fusion (PSF).

SUMMARY OF BACKGROUND DATA: There has been successful implementation of an accelerated recovery protocol for AIS patients undergoing PSF in the western population. No similar studies have been reported in the Asian population.

METHODS: Seventy-four AIS (65 F, 9 M) patients scheduled for PSF surgery were recruited. The accelerated protocol encompasses preoperative regime, preoperative day of surgery counseling, intraoperative strategies, an accelerated postoperative rehabilitation and pain management regime. All patients were operated using a dual attending surgeon strategy. Outcome measures included pain scores at five time intervals, length of stay, and detailed recovery milestones. Any complications or readmissions during the first 4 months postoperative period were recorded.

RESULTS: Mean duration of operation was 2.2 ± 0.3 hours with a mean blood loss of 824.3 ± 418.2 mL. No patients received allogenic blood transfusion. The mean length of stay was 3.6 ± 0.6 days. Surgical wound pain score was 6.4 ± 2.1 at 12 hours, which reduced to 5.0 ± 2.0 at 60 hours. Abdominal pain peaked at 36 hours with pain scores 2.4 ± 2.9. First liquid intake was at 5.2 ± 7.5 hours, urinary catheter removal at 18.7 ± 4.8 hours, sitting up at 20.6 ± 9.1 hours, ambulation at 27.2 ± 0.5 hours, consumption of solid food at 32.2 ± 0.5 hours, first flatus at 39.0 ± 0.7 hours, and first bowel movement at 122.1 ± 2.0 hours. The complication rate was 1.4% due to superficial wound infection with one patient failed to comply with the accelerated protocol.

CONCLUSION: An accelerated recovery protocol following PSF for AIS is feasible without increasing the complication or readmission rates. The total length of stay was 3.6 days and this is comparable with the outcome in western population.
